977 6620 d 22 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
970 6621 d 1 h decky /kernel/trunk/arch/ppc32/ ppc32: get memory map from loader  
967 6621 d 2 h palkovsky /kernel/trunk/ Allowed userspace to include page.h.  
957 6621 d 16 h decky /kernel/trunk/arch/ run ppc32 kernel above 2 GB  
951 6621 d 21 h decky /kernel/trunk/arch/ppc32/ ppc32 boots again (temporarily)  
940 6622 d 17 h jermar /kernel/trunk/ Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader.		  
934 6622 d 19 h decky /kernel/trunk/arch/ppc32/ remove all OpenFirmware bindings from ppc32 kernel code
kernel now runs in real mode (ppc32)		  
867 6640 d 22 h jermar /kernel/trunk/ Move OFW functionality of ppc32 memory_init to genarch so that the code can also be used by sparc64.
sparc64 is now close to broken as it lacks functionality to provide identity mapping for the whole phyisical memory.		  
843 6646 d 16 h palkovsky /kernel/trunk/ Made powerpc to get on PearPC to the version print when compiled with -O1:
- create proper memory zones
- switch to real mode on boot
TODO
- kernel relocation during boot
- autodetection of framebuffer settings (PCI?) - now includes hardcoded
settings for PearPc.		  
833 6650 d 12 h jermar /kernel/trunk/arch/ppc32/include/mm/ Fix ppc32 to at least compile again.  
823 6654 d 13 h jermar /kernel/trunk/ Reimplement ASID stealing logic.
This time, hopefully, with correct synchronization.		  
765 6660 d 15 h jermar /kernel/trunk/ Add PAGE_WIDTH to aid divisions by PAGE_SIZE.  
763 6660 d 21 h jermar /kernel/trunk/ Modify frame.h to use shifting instead of multiplication and division.
Define FRAME_WIDTH for all architectures.		  
760 6661 d 0 h jermar /kernel/trunk/ mips32 is not supposed to allocate page table.
This is done by the generic code now.
Remove PTL0 pointer as it is not needed.

Remove GET_PTL0_ADDRESS from kernel.

Update sparc64 comments in barrier.h.		  
756 6662 d 12 h jermar /kernel/trunk/ Memory management work.
Remove the last (i.e. 'root') argument from page_mapping_insert() and page_mapping_find().
Page table address is now extracted from the first (i.e. 'as') argument.
Add a lot of infrastructure to make the above possible.
sparc64 is now broken, most likely because of insufficient identity mapping of physical memory.		  
727 6674 d 14 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.		  
703 6680 d 23 h jermar /kernel/trunk/ Memory management work.
- vm.* -> as.* (as like address space is, imho, more fitting)
- Don't do TLB shootdown on vm_install(). Some architectures only need to call tlb_invalidate_asid().
- Don't allocate all frames for as_area in as_area_create(), but let them be allocated on-demand by as_page_fault().
- Add high-level page fault handler as_page_fault().
- Add as_area_load_mapping().		  
569 6716 d 14 h jermar /kernel/trunk/ sparc64 work.
Implement functions for reading IMMU and DMMU TLBs.		  
534 6720 d 17 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6720 d 17 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.
